Well, the interface from Oblivion was pretty good, but there werer some things I disliked about it:

First: I hated how gold was handled in Oblivion, it felt a lot better if you could find it in a section of your invintory and could drop it (this could come into play in Skyrim since actors will react to you dropping items, and a fat purse of gold could really draw out somebody you want). What they could do is handle it like it was in Fallout: it appears in your invintory system in everything except with the trade system, at that point it is displayed on the trade window. Done and done.

Two: I would like it if you could toggle having your hotkeys opaque all the time, it kind of helps me remember to use them. That would be awesome.

That's honestly all I have at this point, everyone else's turn...

*points at sig*

Damn you I lost the game. Anyways I would like to see a separate UI for PC, mainly with smaller text. Besides that I would like more UI functions like being able to mark things on the world and local map. Actual notes like "Strong enemy here", etc.

I want Gold to be a lootable item that accumulates in your bags as an item. No weight, but kind of like how it was in Morrowind.

they did that in Fallout 3, so it might carry over to Skyrim. you'd think with the new 3D item preview thing they'd want to show off their sixy new Septim model.

i'd like the ability to remap inventory/map/journal/etc. to more than just F1-F4. smaller font size would be nice, too, but modders will do that within a week anyway so it's not really a big deal.
